[CMake] "Configuring" and "Generating" progress indicator

[Jorrit Schaap]

Hi,

We use cmake (on Linux) on a very large source tree (100+ libs, ~50
executables). The "Configuring" and "Generating" steps take a long time,
which is logical and ok. But, would it be possible to print the "Configuring"
and "Generating" progress to the command line? 

I think it should be possible, because the are progress indicators in the
ccmake ui.

Thanks, Jorrit
